[Tex/LaTex] biblatex: Make title hyperlink to doi url (if available)

biblatexdoihyperref

I'm using biblatex with the standard bibliography style. How or what should I modify so that the title is turned into a link pointing to a suitable doi url? (of course only if the doi is available)

Best Answer

I used the default example bib from the current biblatex documentation which is available on every TeX distribution. The two entries have both a doi entry in the bib file:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[backend=biber]{biblatex} 
\usepackage[colorlinks]{hyperref}
\bibliography{biblatex-examples}
\ExecuteBibliographyOptions{doi=false}
\newbibmacro{string+doi}[1]{%
  \iffieldundef{doi}{#1}{\href{http://dx.doi.org/\thefield{doi}}{#1}}}
\DeclareFieldFormat{title}{\usebibmacro{string+doi}{\mkbibemph{#1}}}
\DeclareFieldFormat[article]{title}{\usebibmacro{string+doi}{\mkbibquote{#1}}}
\begin{document}
A reference to~\cite{kastenholz} and~\cite{sigfridsson}. 
\printbibliography
\end{document}

With the latest biblatex update there is also a star version for \DeclareFieldFormat which refers to all entry types.
